| Auditing of account use and user actions is a critical part of the security architecture. Auditable events must be logged. If the network element becomes unable to write events to the audit log, this is known as an audit processing failure. Audit processing failures include software and hardware errors, failures in the audit capturing mechanisms, and audit storage capacity being reached or exceeded. By immediately displaying an alarm message, potential security violations can be identified more immediately, even when administrators are not logged into the network element
Alerting is based on an anomaly analysis of the IDPS application audit log on the organization's central log server, thus this is not a function performed by the IDPS itself. |
